To help you find more results, we automatically adjust your search criteria for certain queries (for example, if you search for "John Doe born in 1950 in Nebraska" we may include results for "Jerry Doe born in 1950" or "John Doe born in 1950 in Kansas").If you check the "Exact" box we will add extra weight to this criteria, but may still show other close matches to account for estimated dates, nicknames, and transcription errors. We recommend you use this feature when you are confident in the information you are entering.
